Ron Gavlin commented on TUSCANY-1812:
-------------------------------------
After further investigation, what do you think of this approach.
1. Change AttributeImpl.InternalSettingDelegateSequence to be non-static
2. Create BasicFeatureMap and FeatureMapUtil.BasicValidator subclasses whose
constructors accept an add'l ExtendedMetaData parameter. The BasicValidator
subclass will look like its parent's constructor except it will reference the
ExtendedMetaData parameter rather than ExtendedMetaData.INSTANCE.
3. Modify
AttributeImpl.InternalSettingDelegateSequence.createDynamicSetting(InternalEObject
owner) to handle feature style FEATURE_MAP directly rather than calling
super(). It would instantiate the BasicFeatureMap subclass passing its
getExtendedMetaData() which is the correct SDOExtendedMetaDataImpl.
Does this sound reasonable?

> Project: Tuscany
> Issue Type: Bug
> Components: Java SDO Implementation
> Affects Versions: Java-SDO-Next
> Reporter: Ron Gavlin
> Priority: Critical
>
> Below, please find a failing Java test case and its XSD and XML test
> resources. Also, please find the stacktrace from the failing Java test case.
> It is interesting to note that this test does not fail when using dynamic
> SDO. Please comment if you have questions.
